Sir Arthur George Weidenfeld, Baron Weidenfeld is a British publisher, philanthropist, and newspaper columnist. In 1949 he served as political adviser and Chief of Cabinet to Chaim Weizmann.
In 1948, Weidenfeld co-founded the publishing firm Weidenfeld & Nicolson with Nigel Nicolson. The firm published several landmark titles, including Vladimir Nabokov’s “Lolita” and Nicolson’s own controversial autobiography Portrait of a Marriage.
In 1985, Weidenfeld’s publishing interests expanded to the United States, when he acquired the Grove Press in partnership with Ann Getty. Grove later merged with the New York division of Weidenfeld & Nicolson to form Grove Nicolson. In 1991, Weidenfeld & Nicolson’s U.K. branch was sold to the Orion Publishing Group and became Orion’s main non-fiction imprint. In 1993, the U.S. company, Grove Nicolson, merged with the Atlantic Monthly Press to form Grove/Atlantic Inc.
